Imagine diving hundreds of metres into the depths on one breath. Now imagine using this ability to tag great white sharks in the least harmful way possible. William uses free-diving to help scientists tag different shark species around the world.
Every year thousands of blacktip sharks migrate along the coast of South Florida. Marianne will film the aggregation with drones and then use her knowledge of engineering and physics to understand how the animals move. This is the first time that shark-swimming kinematics will be studied in the wild!
Bimini in the Bahamas is home to large populations of sharks. Mariana will observe whether the presence of those sharks affects how turtles use their habitat and whether more turtles means more sharks. Bimini is undergoing intensive development for tourism, so understanding how animals use their space is critical for their conservation.
